(2) Anovulation - Irregular periods are usually accompanied by delayed ovulation OR anovulation (absence of ovulation) in women – this means that the ovaries won't release eggs (ovulation) as they ought to.

(3) Polycystic ovaries – Instead of releasing eggs, the ovaries become enlarged and contain many fluid-filled sacs (follicles) which surround the eggs.

If you have at least two of these features you may be diagnosed with PCOS.
